Maybe..

Another thing I have noticed with WLS (at least for me on a Vodafone network) is that the maps take ages to download. Often when I start it up I have a GPS location right away (GPS arrow appears on screen and is red so has a lock) but then it takes 5-10 minutes to get the map for that location which could also be a problem some people are having.

Other thing just to note as well is that I just leave the "external GPS" application alone (set to None for both ports and manage automatically). For some software you might need to change this but for WLS (at least in WM06 on the touch) you don't need to set this.
